What recommendations are there for most cost-effective ways to acquire lead leads? Specifically, I'm looking for B2B service businesses within 50 miles of Raleigh, NC. To date, most of my deal flow has come through local brokers, CPAs, and advisors I've connected with, but looking to step up my direct outreach.

Would love thoughts on the best service to use; if anyone has extra licenses and wants to share costs and/or sell me a list directly, I'm all ears!
